Family house in Hradec Kralove

Description of the implementation:

At the beginning of the implementation of this project, we faced the problem how to integrate several different devices inside the family house into a Central Control System. We needed to control a hot air heating system based on an ATREA recuperation unit and an underfloor heating system containing a water tank, electrical boiler and fireplace heat exchanger.

It was also needed to control heating of a supply water, including water circulation and purification. On top of that, the owner of the house wanted to install a security system, intelligent lighting system and the system for controlling of the outside sunblinds.

After reviewing the situation with the investor, it was decided to discard a number of autonomous regulators and control units from different manufacturers and integrate control of all devices via central Control System. For this purpose we've used the Tecomat Foxtrot CP1005 PLC unit with expansion modules. This PLC unit has a big advantage, it features an intelligent CIB bus, through which we are able to obtain the data from various electric devices installed in the house (e.g. room thermometers, light switchers, sunblinds or security system).

The result of this installation was a distribution box containing the Tecomat Foxtrot CP1005 PLC, which placed in the basement of the house. This solution provides a reliable control of all intelligent devices from one place. There is a 17" control panel with a touch screen installed on the wall in the foyer. This control panel provides visualization and control of all processes and devices installed in the house.

This solution has several advantages, for example this solution is energy efficient and user-friendly (the owner of the family house can control all the technologies from one place).

The new control system provides control of the following features:

• Automatic lights switching on at a predefined time
• Automatic lights switching of when the owners leave the house
• Automatic outdoor sunblinds lowering after leaving the house
• Automatic supply water heating turning off after leaving the house
• Automatic activation of the "Reduced Heating" operation after leaving the house
• Automatic turn-off of the main water line after leaving the house (in case of washing the laundry or dishes, the main water line is turned off immediately after the washing)
• Instant start of the "Occupancy" operation when the owners leave the house

The user has the possibility to control the system by using the SMS messages. Moreover, the Control System can send information messages about specific events to user's cell phone. Users have also the possibility to display the visualization screens on a remote computer via the Internet.
